I don't know if this might seem crazy to some, but during a Lucid dream state or something very similar when I was in control of the dream I wanted to go backwards through my memory's only something unexpected happen and I experienced my own birth only backwards. I literally was feeling myself being pulled through a tube where at first I didn't know where I was till it stopped. At this point and time I saw a full view of what I was in. I know this sounds strange but it was a interesting experience because I saw everything from that prospective and felt everything.
